Spatial Awareness Biases In Synthetic Vision Systems Displays, Matthew L. Bolton, Ellen J. Bass Jan 2007

Spatial Awareness Biases In Synthetic Vision Systems Displays, Matthew L. Bolton, Ellen J. Bass

International Symposium on Aviation Psychology - 2007

Synthetic Vision Systems (SVS) create a synthetic clear-day view of the terrain in front of ownship to prevent controlled flight into terrain. To investigate how spatial biases manifest themselves in SVS displays, an experiment was conducted. Eighteen pilots made spatial judgments (relative angle, distance, height, and abeam time) regarding the location of terrain points displayed in 112 5-second videos of a SVS head down display. Judgment errors revealed expected and unexpected spatial biases. Knowledge of these biases will allow SVS engineers to compensate for them and to improve spatial awareness in future SVS designs.

An Airline Evaluation Of The Facilitation Skills Assessment Tool [Fsat] As A Device For Training And Assessing Facilitators, Maryjo O. Smith Ph.D., Guy M. Smith Ed.D., Captain Colin Budenberg, Captain John Willats, Captain Pete Griffiths

International Symposium on Aviation Psychology - 2007

Researchers and airline practitioners from the USA and UK collaborated in a four-year project to develop the Facilitation Skills Assessment Tool (FSAT), an instrument to assess the skills of an airline facilitator. The final phase of the FSAT Development Project was the evaluation of FSAT at two airlines – Thomsonfly (formerly Britannia Airways) in the UK and Southwest Airlines in the USA. Statistical analysis allowed the combination of data from both airlines; these 66 assessments demonstrated that FSAT was a valid and reliable instrument for measuring facilitation skills.

Changes In Cognitive And Sensory Abilities Of Older Pilots Parallel Those Observed In The General Population, C.A. Miller, A. Chaparro Jan 2007

Changes In Cognitive And Sensory Abilities Of Older Pilots Parallel Those Observed In The General Population, C.A. Miller, A. Chaparro

International Symposium on Aviation Psychology - 2007

This investigation compares young and older pilots with age-matched controls from the general population on cognitive and sensory abilities. Cognitive assessments included short-term and long-term memory, learning, delayed recognition and mental rotation. Sensory measures included visual acuity, contrast sensitivity, auditory thresholds, speech intelligibility and tactile sensitivity. Significant differences in contrast sensitivity was obtained as a function of age and pilot status. Also, young pilots (24-42 years) have greater tactile sensitivity than older pilots (64-88 years), and both non-pilot groups. In general, younger participants performed better on the assessments than the older subjects regardless of pilot status. Although, the mean differences …

Testing A Maneuver Space-Based Collision Avoidance System: Experiment 1, William R. Knecht Jan 2007

Testing A Maneuver Space-Based Collision Avoidance System: Experiment 1, William R. Knecht

International Symposium on Aviation Psychology - 2007

A new data visualization technology is demonstrated for en-route tactical aircraft separation maintenance. This technology displays maneuver space (MS), a nonveridical coordinate space based on the four key maneuver elements of heading, speed, altitude, and available maneuver time. In this first major test of a prototype 4D collision avoidance system (4CAS), eight licensed general aviation pilots each flew eight simulated free flight scenarios, with the goal of deviating as little as possible from a pre-assigned flight path, while still maintaining standard separation from traffic. Compared to a cockpit display of traffic information (CDTI), the CDTI+4CAS condition showed performance advantage for …

The Effects Of Gps And Moving Map Displays On Pilot Navigational Awareness While Flying Under Vfr, Stephen M. Casner Jan 2007

The Effects Of Gps And Moving Map Displays On Pilot Navigational Awareness While Flying Under Vfr, Stephen M. Casner

International Symposium on Aviation Psychology - 2007

GPS and moving map displays are popularly believed to increase pilot navigational awareness – further empowering the already aware pilot with additional information about their position and surroundings. In a first experiment, pilots’ beliefs about their own navigational awareness were compared to their measured awareness while navigating along a cross-country route. The results demonstrate a familiar out-of-the-loop effect and a marked disparity between what pilots believed and how they performed. In a second experiment, different pilots were asked to more actively participate in the navigation process while performing the same navigational task. The results indicate that this additional involvement significantly …

The Development And Molecular Expression In Mammalian Cells Of An Ha-Tagged Plasmid Encoding For The Target Of Rapamycin (Mtor), Kevin S. Dougherty

Browse all Theses and Dissertations

The protein kinase mammalian Target of Rapamycin (mTOR) is a master controller of cell growth and proliferation due to its ability to integrate growth signals and regulate translation through 4E-BP1 and p70-S6K. We developed four phCMV2-HA-tagged plasmids to overexpress TOR in mammalian cells: Wild Type, D2357E (Kinase Dead), R2109A (PA Binding Deficient) and, S2035T (Rapamycin Resistant) each verified by restriction enzyme digestion and direct sequencing. Plasmid DNA was overexpressed in COS-7 cells and the 289 kDa protein detected in Western blots developed with anti-HA and anti-mTOR antibodies. Kinase activity of the overexpressed protein was detected by in vitro phosphorylation of …

Caenorhabditis Briggsae Methods, Scott Everet Baird, Helen M. Chamberlin Dec 2006

Caenorhabditis Briggsae Methods, Scott Everet Baird, Helen M. Chamberlin

Biological Sciences Faculty Publications

Caenorhabditis briggsae is being developed in parallel to C. elegans as a model system, primarily for the study of evolution. Like C. elegans, C. briggsae is a protandrous hermaphrodite and like C. elegans, its genome has been sequenced. From this point, these two model systems diverge. The development, behavior, and physiology of C. elegans have been characterized through tens of thousands of genetic and molecular studies. Genetic and molecular characterizations of C. briggsae are relatively few. Experimental resources in C. elegans include a high density recombination map that is well integrated with the genome sequence. The C. briggsae …

Fracture Of The Scapula With Intrathoracic Penetration In A Skeletally Mature Patient, Cary C. Schwartzbach, Hani Seoudi, Amy E. Ross, Kimberly M. Hendershot, Linda Robinson, Alireza Maekzadeh Dec 2006

Fracture Of The Scapula With Intrathoracic Penetration In A Skeletally Mature Patient, Cary C. Schwartzbach, Hani Seoudi, Amy E. Ross, Kimberly M. Hendershot, Linda Robinson, Alireza Maekzadeh

Department of Surgery Faculty Publications

To our knowledge, intrathoracic displacement of a fractured scapula has only been described in two reports involving adolescents1,2. We present the case of a skeletally mature adult with a scapular fracture that penetrated the thoracic cage without causing a pneumothorax. We speculate as to how the adult scapula can deform in a manner consistent with this rare injury. As the patient had advanced Alzheimer disease, the family consented to the publication of data concerning this case.

Soluble Amyloid Oligomers Increase Bilayer Conductance By Altering Dielectric Structure, Yuri Sokolov, J. Ashot Kozak, Rakez Kayed, Alexandr Chanturiya, Charles G. Glabe, James E. Hall Nov 2006

Soluble Amyloid Oligomers Increase Bilayer Conductance By Altering Dielectric Structure, Yuri Sokolov, J. Ashot Kozak, Rakez Kayed, Alexandr Chanturiya, Charles G. Glabe, James E. Hall

Neuroscience, Cell Biology & Physiology Faculty Publications

The amyloid hypothesis of Alzheimer's toxicity has undergone a resurgence with increasing evidence that it is not amyloid fibrils but a smaller oligomeric species that produces the deleterious results. In this paper we address the mechanism of this toxicity. Only oligomers increase the conductance of lipid bilayers and patch-clamped mammalian cells, producing almost identical current-voltage curves in both preparations. Oligomers increase the conductance of the bare bilayer, the cation conductance induced by nonactin, and the anion conductance induced by tetraphenyl borate. Negative charge reduces the sensitivity of the membrane to amyloid, but cholesterol has little effect. In contrast, the area …

Team-based learning (TBL) is a well-defined instructional strategy that allows a single instructor to teach by conducting multiple small groups simultaneously in the same classroom. Learners actively participate in and out of class as they move through three phases: independent study assignments, readiness assurance testing, and group activities that force them to put knowledge into practice. Students prepare in advance by reading an assigned article. Class time is shifted away from learning facts and toward application and integration of information. The instructor retains control of content and acts as both facilitator and content expert. This TBL program is designed to …

Combining An Autologous Peripheral Nervous System “Bridge” And Matrix Modification By Chondroitinase Allows Robust, Functional Regeneration Beyond A Hemisection Lesion Of The Adult Rat Spinal Cord, John D. Houle, Veronica J. Tom, Debra A. Mayes, Gail Wagoner, Napoleon Phillips, Jerry Silver

Neuroscience, Cell Biology & Physiology Faculty Publications

Chondroitinase-ABC (ChABC) was applied to a cervical level 5 (C5) dorsal quadrant aspiration cavity of the adult rat spinal cord to degrade the local accumulation of inhibitory chondroitin sulfate proteoglycans. The intent was to enhance the extension of regenerated axons from the distal end of a peripheral nerve (PN) graft back into the C5 spinal cord, having bypassed a hemisection lesion at C3. ChABC-treated rats showed (1) gradual improvement in the range of forelimb swing during locomotion, with some animals progressing to the point of raising their forelimb above the nose, (2) an enhanced ability to use the forelimb in …

Substratum As A Driver Of Variation In Periphyton Chlorophyll And Productivity In Lakes, Yvonne Vadeboncoeur Jun 2006

Substratum As A Driver Of Variation In Periphyton Chlorophyll And Productivity In Lakes, Yvonne Vadeboncoeur

Biological Sciences Faculty Publications

Quantifying periphyton (attached algal) contributions to autotrophic production in lakes is confounded by properties of substratum that affect community biomass (as chlorophyll content) and productivity. We compared chlorophyll content and productivity of natural algal communities (phytoplankton, epipelon, epilithon, epixylon, and epiphyton) experiencing high (>10%) incident radiation in lakes in the US, Greenland, and Quebec, Canada. Chlorophyll content and productivity differed significantly among regions, but they also differed consistently among communities independent of region. Chlorophyll content of periphyton on hard substrata (rocks and wood) was positively related to water-column total P (TP), whereas chlorophyll content of algae on sediment (epipelon) …

Feasibility Of Gdaha Hospitals Meeting The Surge Capacity And Capability Requirements Of An Avian Flu Pandemic In The Miami Valley, Raymond P. Ten Eyck May 2006

Feasibility Of Gdaha Hospitals Meeting The Surge Capacity And Capability Requirements Of An Avian Flu Pandemic In The Miami Valley, Raymond P. Ten Eyck

Master of Public Health Program Student Publications

Hospital surge capacity is a crucial portion of disaster preparedness planning within a community. The demands generated by a disaster require additional capacity, in the form of beds, equipment, personnel, and special capabilities. The scope and urgency of these requirements must be balanced with a practical approach addressing cost and space concerns. The advent of new infectious disease threats, particularly an avian flu pandemic, have reinforced the need to be prepared for a prolonged surge, lasting six to eight weeks, in addition to the shorter duration surges required for industrial accidents, tornados, chemical disasters and terrorists. Using a standardized data …
